Technical Field

[0001] This invention relates to the field of snow removal technology, specifically to a dual-position hydraulic folding snow loading machine. Background Technology

[0002] With the acceleration of urbanization and the frequent occurrence of extreme weather, winter snowfall has a serious impact on traffic and public safety in areas such as municipal sanitation, highways, and airports, creating a rigid demand for specialized snow removal equipment. Efficient and convenient snow loading equipment has become the core equipment required for winter snow removal operations.

[0003] The following problems were found in the relevant technologies: the connection structure of the snow loading machines on the market is simple, the frictional resistance at the rotating connection is large, most of them are fixed structures, do not have folding function, occupy a lot of space during transportation and storage, have poor flexibility, and are inconvenient to adjust the angle, making it difficult to accurately guide the snow into the dump truck. In response, the present invention provides a dual-position hydraulic folding snow loading machine.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the issue of snow loading efficiency in the prior art, this invention provides a dual-position hydraulic folding snow loading machine, employing a dual-position independent hydraulic adjustment mechanism combined with a multi-channel transmission structure to improve snow loading efficiency. The specific technical solution is as follows: A dual-position hydraulic folding snow loading machine includes an integrated frame connected to the front end of a work vehicle. A transmission arm folded to its top is rotatably mounted on the integrated frame. A snow-throwing bucket is rotatably mounted on the top of the outer wall of the transmission arm and connected to its outlet. The snow-throwing bucket is folded down onto the outer wall of the transmission arm. Rotary adjustment mechanisms for adjusting the angle between the transmission arm and the snow-throwing bucket are respectively provided on the integrated frame and the outer wall of the transmission arm. A snow shovel is fixed to the front side of the integrated frame, and a collection channel communicating with the transmission arm is opened on the inner wall of the snow shovel. A bidirectional auger is rotatably arranged in the inner cavity of the snow shovel to collect snow into the collection channel.

[0006] In the above technical solution, the inner cavity of the transmission arm is rotatably equipped with a transmission auger, the bottom of the outer wall of the transmission arm is fixed with an inner rotating channel, the outer wall of the inner rotating channel is rotatably equipped with an outer rotating channel fixed to the outer wall of the snow collection shovel, and the outer rotating channel is connected to the collection channel.

[0007] The outer wall of the integrated frame is fixed with expanded wing plates located on both sides of the snow collection shovel.

[0008] The top of the outer wall of the snow shovel is fixed with reinforcing ribs that extend to the integrated frame.

[0009] The rotation adjustment mechanism includes hydraulic cylinders that are rotatably mounted on the integrated frame and the transmission arm, respectively, with the movable ends of the two hydraulic cylinders rotatably mounted on the outer walls of the transmission arm and the snow-throwing bucket.

[0010] The top of the outer wall of the transmission arm is fixed with a material guide bin, and the bottom of the material guide bin is provided with a discharge port for feeding material into the snowball thrower.

[0011] The bidirectional auger is evenly provided with tooth grooves.

[0012] A cable gathering tube is provided through the rear side of the integrated frame. The cable gathering tube is connected to the integrated frame through a movable component. A protective component is provided on the inner side of the integrated frame and sleeved on the outside of the cable gathering tube.

[0013] The protective assembly includes a transmission frame sleeved on the outer wall of the line coiling cylinder. The transmission frame and the integrated frame are both fixed with steering seats on their opposite sides. An outer cylinder is provided between the two coaxial steering seats. Inner support rods are embedded at both ends of the outer cylinder. A movable part embedded in the steering seat is fixed at the other end of the inner support rod. A spring sleeved on the outside of the inner support rod is provided between the movable part and the outer cylinder.

[0014] The movable component includes a movable cavity formed inside the rear side of the integrated frame, and a follow-up limiting plate that is slidably disposed on the inner wall of the movable cavity is sleeved on the outer wall of the line gathering tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The transfer arm and snow-throwing bucket adopt a foldable design. When not in use, they can be folded to the top of the integrated frame and the outer wall of the transfer arm, which greatly reduces transportation and storage space and lowers storage and transportation costs. The dual-position independent hydraulic adjustment mechanism drives the transfer arm and snow-throwing bucket to rotate through two hydraulic cylinders respectively. The angle of both can be precisely adjusted to ensure that the snow can smoothly enter the snow-throwing bucket from the snow shovel through the transfer arm and be accurately fed into the dump truck, avoiding snow spillage and improving the accuracy of snow loading.

[0016] 2. The snowplow's blade is angled and has a wear-resistant rubber strip on the side in contact with the ground. This ensures that snow is shoveled in smoothly, avoids abrasion on the ground, and also acts as a buffer to reduce the impact on the snowplow. The detachable expansion wings on both sides can be flexibly installed and removed according to operational needs, effectively expanding the snow collection range, reducing the number of times the work vehicle needs to travel, and improving snow removal efficiency. The reinforcing ribs further improve the overall strength and stability of the snowplow, preventing deformation and damage from long-term operation.

[0017] Third, the uniform grooves on the bidirectional auger can disrupt the complete contact surface of the snow-covered surface, break the adsorption force of the ice and snow water film, achieve self-cleaning, and prevent snow from hardening and adhering. At the same time, it can cut and break up the clumps of snow and thin ice layers to prevent material blockage and improve the smoothness of feeding. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The following are specific implementation cases and appendices. Figure 1-8 The present invention will be further described, but the present invention is not limited to these embodiments.

[0021] A dual-position hydraulic folding snow loader includes an integrated frame 1 connected to the front end of a work vehicle. The integrated frame 1, serving as the core load-bearing structure of the snow loader, is welded from high-strength steel and features a frame-like design, possessing sufficient load-bearing strength and impact resistance to effectively withstand the impact of snow accumulation, the weight of various components, and the driving force of the hydraulic mechanism during operation. A connecting lug is fixed to the rear side of the integrated frame 1 for rotatable connection to the front side of the work vehicle. The connecting lug is an integral forged structure, welded and fixed to the integrated frame 1. A through-hole is provided on the connecting lug, allowing for rotatable connection with the connecting mechanism at the front end of the work vehicle via a pin. A wear-resistant bushing is provided at the rotatable connection point to reduce rotational friction, ensuring that the equipment can flexibly adjust its working angle according to the direction of travel of the work vehicle, adapting to different working trajectory requirements.

[0022] The integrated frame 1 is rotatably equipped with a transmission arm 2 that folds to its top. The transmission arm 2 can rotate laterally with the integrated frame 1. Two rotating shafts are respectively set on the front and rear sides of the transmission arm 2. One of them rotates on the rear inner wall of the integrated frame 1, and the other rotating shaft is supported by an L-shaped bracket fixed to the inner wall of the integrated frame 1 and is located above the outer rotating channel 23. The two rotating shafts enable the transmission arm 2 to rotate to a position perpendicular to the integrated frame 1.

[0023] A snow bucket 3 is rotatably mounted on the top of the outer wall of the transmission arm 2 and is connected to its outlet. The snow bucket 3 is stacked on the outer wall of the transmission arm 2. A bracket is fixedly installed on the right side of the transmission arm 2 near the top. A rotating shaft is mounted on the bracket. A connecting seat fixed to the bottom of the snow bucket 3 is sleeved on the outer wall of the rotating shaft, so that the snow bucket 3 can rotate to a position perpendicular to the transmission arm 2.

[0024] The outer walls of the integrated frame 1 and the transmission arm 2 of the snow bucket 3 are respectively provided with a rotary adjustment mechanism for adjusting the angle between the transmission arm 2 and the snow bucket 3. During the snow removal process, the transmission arm 2 and the snow bucket 3 are driven to rotate by the two independent rotary adjustment mechanisms, so that the snow enters the transmission arm 2 from the snow collection shovel 4, enters the snow bucket 3 through the transmission arm 2, and then enters the snow bucket 3. The angle of the snow bucket 3 is adjusted to the tipping bucket of the dump truck, so that the snow falls on the tipping bucket.

[0025] A snow shovel 4 is fixed to the front of the integrated frame 1, and a collection channel 5 connected to the transmission arm 2 is opened on the inner wall of the snow shovel 4. The blade of the snow shovel 4 is inclined, and a wear-resistant rubber strip is provided on the side that is in contact with the ground. This ensures that the snow can be shoveled in smoothly, avoids the blade from abrading the ground, and also provides a certain buffering effect to reduce the impact on the snow shovel 4 during operation.

[0026] The inner cavity of the snow shovel 4 is equipped with a bidirectional auger 6 that collects snow into the collection channel 5. The collection point of the bidirectional auger 6 corresponds to the collection channel 5. The bidirectional auger 6 is driven by a motor located on the side of the integrated frame 1. As the bidirectional auger 6 rotates continuously, the snow shovel 4 transfers the snow collected in the shovel cavity to the collection channel 5. The collection channel 5 then transports the snow to the inlet of the transfer arm 2, where the auger inside the transfer arm 2 transports it to the snow dump 3. Finally, the snow dump 3 guides the snow dump truck onto the dump truck.

[0027] The inner cavity of the transmission arm 2 is rotatably equipped with a transmission auger 21, and the bottom of the outer wall of the transmission arm 2 is fixed with an inner rotating channel 22. A motor is fixed at the bottom of the transmission arm 2, and the output shaft of the motor is fixedly connected to the central shaft of the transmission auger 21. The outer wall of the inner rotating channel 22 is rotatably equipped with an outer rotating channel 23 fixed to the outer wall of the snow collection shovel 4, and the outer rotating channel 23 is connected to the collection channel 5.

[0028] The outer rotating channel 23 is sleeved on the outside of the inner rotating channel 22, so that the outer rotating channel 23 rotates against the outside of the inner rotating channel 22. The outer wall of the inner rotating channel 22 is fixed with a sealing ring, so that the snow enters the outer rotating channel 23 from the collection channel 5 on the snow shovel 4, and then enters the inner rotating channel 22 from the outer rotating channel 23. During the rotation of the transmission arm 2, the outer rotating channel 23 rotates against the outer wall of the inner rotating channel 22.

[0029] It is worth noting that the outer wall of the integrated frame 1 is fixed with expansion wing plates 41 located on both sides of the snowplow 4. The expansion wing plates 41 are fixed outward, increasing the range of the snowplow 4. The expansion wing plates 41 are fixed with bolts and can be installed or removed according to operational needs. The expansion wing plates 41 extend horizontally outward, which can effectively increase the snow collection range of the snowplow 4, reduce the number of times the work vehicle needs to travel, and improve snow removal efficiency.

[0030] The top of the outer wall of the snow shovel 4 is fixed with a reinforcing rib 42 extending to the integrated frame 1. The reinforcing rib 42 improves the overall strength of the snow shovel 4 and ensures the overall stability.

[0031] The rotation adjustment mechanism includes hydraulic cylinders 7, which are rotatably mounted on the integrated frame 1 and the transmission arm 2, respectively. The movable ends of the two hydraulic cylinders 7 are rotatably mounted on the outer walls of the transmission arm 2 and the snow bucket 3, respectively. After the hydraulic cylinders 7 are activated, the movable ends of the hydraulic cylinders 7 drive the snow bucket 3 or the transmission arm 2 to rotate, thereby adjusting the angle of the transmission arm 2 and the snow bucket 3.

[0032] In addition, a guide bin 24 is fixed to the top of the outer wall of the conveying arm 2, and a discharge port 25 for feeding snow onto the snowdrift 3 is opened at the bottom of the guide bin 24. The discharge port 25 is located at the bottom of the guide bin 24, and the horizontal inlet of the discharge port 25 is fixed to the top of the outer wall of the conveying arm 2, so that the snow conveyed on the conveying arm 2 falls into the guide bin 24 and then falls into the snowdrift 3 through the discharge port 25 below the guide bin 24.

[0033] In addition, the bidirectional auger 6 is uniformly provided with grooves 61. Snow and ice fragments contain a lot of moisture and easily stick to the surface of the auger blades, causing the auger to seize up, block the conveyor, and slip on the pile. The uniform grooves 61 can disrupt the complete contact surface of the material, break the adsorption force of the ice and snow water film, and form airflow and gap shearing during operation to achieve self-cleaning and prevent snow from hardening and adhering. The grooves 61 form a staggered cutting and scraping structure. When the auger rotates, the edges of the grooves 61 can cut and break up the clumps of snow, thin ice layers, and frozen snow, preventing large pieces of ice and snow from blocking the feed inlet and improving the smoothness of snow feeding.

[0034] A cable gathering tube 8 is installed through the rear side of the integrated frame 1. The cable gathering tube 8 is connected to the integrated frame 1 via a movable component. A protective component is installed inside the integrated frame 1 and sleeved on the outside of the cable gathering tube 8. During operation, all cables are gathered together by the cable gathering tube 8, which is protected by the protective component to prevent damage.

[0035] Furthermore, the protective assembly includes a transmission frame 81 sleeved on the outer wall of the line coiling tube 8. The transmission frame 81 and the opposite surface of the integrated frame 1 are both fixed with steering seats 82. An outer cylinder 83 is provided between the two coaxial steering seats 81. The outer cylinder 83 is sleeved on the outside of the two inner support rods 84, so that the outer cylinder 83 slides against the outer wall of the inner support rod 84.

[0036] Both ends of the outer cylinder 83 are embedded with inner support rods 84. The other end of each inner support rod 84 is fixed with a movable part 85 embedded inside the steering seat 82. A spring 86, sleeved on the outside of the inner support rod 84, is provided between the movable part 85 and the outer cylinder 83. A spherical cavity is formed on the surface of the steering seat 82, and the movable part 85 is spherical, allowing it to rotate freely within the cavity of the steering seat 82. The elastic deformation of the spring 86 provides a buffering effect, protecting the cable coiling cylinder 8.

[0037] The movable component includes a movable cavity 87 located inside the rear side of the integrated frame 1, and a follower limiting plate 88 that is slidably disposed on the inner wall of the movable cavity 87 is sleeved on the outer wall of the cable gathering tube 83. During the movement of the cable gathering tube 83, the cable gathering tube 83 causes the follower limiting plate 88 to slide within the movable cavity 87.

[0038] This embodiment is a dual-position hydraulic folding snow loader. The working principle is as follows: First, the folded transmission arm 2 and snow thrower 3 are driven to rotate through the rotation adjustment mechanism, so that the transmission arm 2 is adjusted to be perpendicular to the integrated frame 1 and the snow thrower 3 is adjusted to be perpendicular to the transmission arm 2. At the same time, according to the snow collection needs, the expansion wing plates 41 on both sides of the snow collection shovel are installed or removed to expand the snow collection range. Then, after the equipment is started, during the operation of the vehicle, the snow shovel 4 is in contact with the ground through the inclined shovel mouth, and the wear-resistant rubber strip plays a role in buffering and protecting the ground, shoveling the snow on the ground into the shovel cavity; at the same time, the motor on the side of the integrated frame 1 drives the bidirectional auger 6 inside the snow shovel 4 to rotate, and the uniform grooves 61 on the auger cut and break up the clumps of snow and thin ice layers, break the adsorption force of the ice and snow water film, prevent the snow from sticking together, achieve self-cleaning, and at the same time, gather the snow in the shovel cavity towards the collection channel; Secondly, the snow enters the outer transfer channel 23 through the collection channel 5, and is then transported to the transfer arm 2 through the cooperation of the outer transfer channel 23 and the inner transfer channel 22. The motor at the bottom of the transfer arm 2 drives the transfer auger 21 to rotate, transporting the snow along the transfer arm 2 to the top guide bin 24, and then it falls into the snow throwing bucket 3 through the discharge port 25 at the bottom of the guide bin 24. Finally, the snowball 3 falls onto the tipper of the dump truck.
